Ownership-based data security transaction method and system

Abstract

The invention discloses an ownership-based data security transaction method and system. The method comprises: ownership encryption is carried out on data provided by a data owner and the processed data are stored; a data characteristic is extracted and registration is carried out; when a transaction application is received, transaction negotiation is carried out and a transaction contract is generated based on a negotiation content; transaction payment is carried out and ownership authorization is carried out on a data applicant; data-ownership-based recording is carried out on a whole transaction process; whether the data has multiple ownerships is determined; if the data has only one ownership, the operation is ended; and if the e data has multiple ownerships, data values are allocated to a plurality of data ownerships. Data encryption and transaction are carried out based on the ownership and the ownership conversion to provide a foundation for profit distribution after data transaction; the transaction behaviors of data owners and data applicants are supported; benefits of all data obligees are guaranteed by providing the method; a problem of loss of branch transaction information realized by the block chain technology is solved; and because the transaction data are in an encryption state, the safety is high.

Description

technical field [0001] The invention relates to the fields of information security technology and data transaction, in particular to a data security transaction method and system based on ownership.

Problems solved by technology

In the data trading market, due to unclear data ownership and illegal data transactions, it is difficult to guarantee the distribution of data owners' interests after data transactions, resulting in damage to personal interests, corporate interests, social interests, and even national interests.

Traditional access applications use the platform to authorize permissions through passwords and other methods. Once sensitive data is leaked, it cannot be traced and held accountable, which will affect personal interests, corporate interests, social stability, and national security.
